摘要:
为揭示煤矸石山复垦地不同植被下草本植物群落与环境因子的关系,采用TWINSPAN分类、DCA排序和物种多样性分析方法,对阳泉矿区五矿2座不同复垦年限(2003、2013)煤矸石山复垦地不同植被下草本植物群落60个植物样方的数据进行了分类、排序与物种多样性研究。结果显示:(1) TWINSPAN分类将该复垦地不同植被下草本植物群落分为12个群丛类型,群丛—Ⅴ位于复垦年限(2013a)较短的矸石山,群丛—Ⅻ位于复垦年限(2003a)较长的矸石山;(2) 样方的DCA排序第一轴反映了复垦年限变化,沿DCA排序第一轴从左往右煤矸石山复垦年限逐渐缩短;DCA第二轴反映了复垦地地形的变化,沿DCA排序第二轴从上到下煤矸石山复垦地由平台→边坡;(3) 不同植被下草本植物群丛的物种多样性表现为平台>边坡(即群丛>群丛、群丛>群丛),乔木林下>灌草丛下(群丛>群丛),复垦年限较长的群丛>复垦年限较短的群丛,表明植被类型、复垦年限、地形对煤矸石山复垦地不同植被下草本植物群丛物种多样性影响明显。随着复垦年限的增长,群丛向更加稳定、多样的方向更替。
Abstract:
In order to reveal the relationship of herbaceous plant communities under different plantations and environmental factors on the reclaimed coal gob piles, 60 quadrat data of herbaceous plant communities under different plantations on the two reclaimed coal gob piles (revegetated in 2013 and 2003, respectively) at No.5 mine in the Yangquan mining area were analyzed by using the methods of TWINSPAN, DCA and species diversity. The results showed that: (1) the herbaceous plant communities under different plantations were classified into 12 communities (associations) by TWINSPAN, in which the communities Ⅰ-Ⅴ were located in the coal gob piles revegetated in 2013, and the communities Ⅵ-Ⅻ were located in the coal gob piles revegetated in 2003; (2) the results of DCA ordination of 60 quadrats clearly reflected the relationship between the distribution patterns of herbaceous plant communities under different plantations and environmental gradients; the first DCA axes represents a gradient in time since restoration, that is, revegetated age of herbaceous plant communities under different plantations gradually decreased from left to right along the first DCA axis. The second DCA axis represents a gradient in slope, that is, the terrain of the reclaimed coal gob piles changed from the platform to slope along the second DCA axis from the top to the bottom; (3) the species diversity of herbaceous plant communities under different plantations showed that the one on the platform of the reclaimed coal gob piles > the one on the slope (i.e., community Ⅴ > community Ⅱ, community Ⅻ > community Ⅶ), under arbor plantations > under shrub and herbs plantations (i.e., community Ⅻ > community Ⅵ), community Ⅻ revegetated in 2003 > community Ⅴ revegetated in 2013, which indicated that the plantation types, revegetated age and terrain of coal gob piles had significant effect on the species diversity of herbaceous plant communities under different plantations on the reclaimed coal gob piles.
